The utility model relates to an automatic weighing device used for weighing various crops such as tobaccos, etc. The utility model comprises an outer case, a machine core and a weighing platform. The weighing platform is provided with a pressure sensor, and the machine core comprises a preamplification, an analog-to-digital conversion and a central controller 4. The crops are weighed on the weighing platform, and an electrical signal is generated by the sensor.Through the preamplification and the analog-to-digital conversion, the electrical signal is processed by the central controller. The weight, the grade, and the amount of money of the crops are displayed, and the datum are printed automatically at the same time , avoiding hunman errors. [#92214353#] The utility model relates to a full automatic electrothermal exchange vapor generator, which has the functions of steam generation, self control, inlet water processing and steam storage ,and the utility model has the function of the digital display of the transistor such as the overrun alarm of the high-low water level, the automatic stopping of the pump of the high water level, the automatic shutdown of the electrothermal element circuit of the low water level and the overpressure, etc. The device uses electricity as energy source and water as medium.Water is heated into the saturated vapor with the pressure from 0Mpa to 4MPa and the temperature from 0DEG. C to 250DEG. C. The utility model has the advantages of safety and wide use.
